Belimo H780S - 3-way globe valve

Belimo H780S – 3-way globe valve

Flanged valve for closed water systems. It can operate as a mixing valve from A+B to AB or as a diverting valve from AB to A+B; permissible pressure values in diverting mode are lower than in mixing mode.

Key technical data

• DN 80, PN 16, Kvs 100 m³/h; stroke 30 mm.
• Medium: water, water with up to 50% vol. glycol.
• Medium temperature: 5...150°C [41...302°F]. Temperature note: 120°C at up to 1600 kPa; 150°C at up to 1400 kPa.
• Flow characteristic: A – AB equal percentage, B – AB linear.
• Permissible leakage: A – AB max. 0.05% of Kvs value; B – AB max. 1% of Kvs value.
• Pipe connection: flange according to ISO 7005-2.
• Body: EN-GJL-250 (GG 25) with protective coating. Closing element, stem and seat: stainless steel; stem seal: PTFE V-ring.

Installation is permitted from the vertical to the horizontal position relative to the stem; installation with the stem pointing downwards is not permitted. Maximum differential pressure and closing pressure depend on the actuator used.
